摘要:
In an overdischarge detection device which is connected between positive and negative load current lines for connecting a chargeable electric cell with a load and which comprises an overdischarge detection circuit including a voltage comparing section for detecting that a cell voltage of the electric cell falls below a threshold voltage to prohibit discharging operation, an adjusting circuit connected to the overdischarge detection circuit detects a particular voltage of a specified part that corresponds to a load current varying in response to relative weight of the load to adjust the threshold voltage on the basis of the particular voltage. Preferably, the adjusting circuit may be constructed so as to clamp the threshold voltage when the particular voltage is higher than a predetermined voltage.

A secondary battery protection unit comprises a discharge switch (41) and a charge switch (42) inserted in an electric path between a positive terminal (B1) and a negative terminal (B2) together with secondary cells (1 and 2) connected in cascade to the discharge and the charge switches (41 and 42), overcharge detection circuits (45 and 46), and an activation control circuit (17) including a current mirror circuit. The activation control circuit (17) detects a voltage difference between both ends of a combination or one of the discharge and the charge switches (41 and 42) to judge whether or not the secondary cells perform a charging operation or a discharging operation. Only during the charging operation, the activation control circuit (17) makes the current mirror circuit supply a bias voltage to the overcharge detection circuits (45 and 46) to allow activation thereof. During the discharging operation, supply of the bias voltage is inhibited to save excessive power consumption.

A protection circuit for an electric cell comprises an overcharge detection circuit (43-1, 43-2) and an overdischarge detection circuit (44-1, 44-2) both of which are connected to a chargeable electric cell (41, 42) to detect an overcharged condition and an overdischarged condition of the electric cell (41, 42), respectively. A switch (S11, S12) is inserted in a power supply line of the chargeable electric cell (41, 42) and is turned off, when the overcharge detection circuit (43-1, 43-2) or the overdischarge detection circuit (44-1, 44-2) detects the overcharged or the overdischarged condition, thereby inhibiting a charging or a discharging operation. At least the overcharge detection circuit (43-1, 43-2) of the above-mentioned two detection circuits (43-1, 43-2, 44-1, 44-2) is connected to a timing signal producing circuit (45) for supplying a first timing signal having a first duration t1 for defining an operation timing thereof, and to a processing circuit (46) for processing an output signal of the overcharge detection circuit (43-1, 43-2) activated by the first timing signal to judge the presence or absence of an overcharged condition and for turning off the switch (S11) upon Judgement of the presence of the overcharged condition.

摘要:
To recommend an item which is highly unexpected to a user because its similarity to user preferences is low and which is useful to the user. A rule that modifies a set of keywords for recommending an item is randomly applied, and a keyword which a user does not prefer is added and a keyword which a user prefers is removed, and then this recommendation result is mixed with a recommendation result of a set of keywords before the above modification, and the mixed result is presented to a user and at the same time the application probability of a rule is learned on the basis of the user's evaluation to a recommended item.

An ink-jet recording apparatus according to one aspect comprises: a movable supporting member slidable in a conveying direction of a recording medium while supporting the recording medium to follow the recording medium conveyed; and an interlocking mechanism configured to control a movement of the movable supporting member. The interlocking mechanism is operable to: position the movable supporting member in a predetermined upstream position in the conveying direction when the recording medium is conveyed to the predetermined upstream position; retain the movable supporting member in the predetermined upstream position until the recording medium overhangs the movable supporting member to cover a contact portion and at least a part of a non-contact portion; and slide the movable supporting member toward a downstream side in the conveying direction while supporting an edge of the recording medium with the conveyance of the recording medium.

摘要:
An image recording apparatus has a recording head, a transporting passage, a paper support section, a pair of discharge rollers and a reverse-transporting mechanism. The paper support includes a main supporting member and an auxiliary supporting member disposed on the upstream side of the main supporting member. An opening can be formed between the two supporting members. The pair of discharge rollers can be rotated reversely, and one of the supporting members can be inclined. This makes it possible to transport backward, through the opening to the reverse-transporting mechanism, a recording medium with an image recorded on one side of the medium. The reverse-transporting mechanism leads the medium to the transporting passage and transports it again toward the recording head. Having a small number of parts and a simple structure, the image recording apparatus enables double-sided image recording.
